  <body>
    <p>This guide describes how to secure a Greenplum Database system. The guide assumes knowledge
      of Linux/UNIX system administration and database management systems. Familiarity with
      structured query language (SQL) is helpful.</p>
    <note type="important" otherprops="pivotal">Because Tanzu Greenplum is based on PostgreSQL,
      certain commercial security scanning software, when trying to identify Tanzu Greenplum
      Database vulnerabilities, may use a PostgreSQL database profile. The reports generated by
      these tools can produce misleading results, and cannot be trusted as an accurate assessment of
      vulnerabilities that may exist in Tanzu Greenplum. For further assistance, or to report any
      specific Tanzu Greenplum security concerns, refer to the <xref
        href="https://tanzu.vmware.com/security" format="html" scope="external">VMware Tanzu
        Security Response Center</xref> guidelines.</note>
    <p>Because Greenplum Database is based on PostgreSQL 9.4, this guide assumes some familiarity
      with PostgreSQL. References to <xref
        href="https://www.postgresql.org/docs/9.4/index.html" scope="external" format="html"
          ><ph>PostgreSQL documentation</ph></xref> are provided throughout this guide for features
      that are similar to those in Greenplum Database.</p>
    <p>This information is intended for system administrators responsible for administering a
      Greenplum Database system.</p>
